2006 hemi. 100,000 on Jasper engine 202,000 on vehicle. Over the last 9 months I've gone through 4 crank position sensors. Problem began with occasional hard starting. Engine would crank fine but no start. No codes. I would try this a few times then push gas pedal to the floor and it would start and run rough and CEL would come on. CPS changed and same thing. Oil pressure sensor code came on. Replaced it and ran fine for a month. Same thing again several times but new CPS fixed it each time. Each CPS would last about a month. Tried Standard and Echlin sensors all lasted a month. Then put in a Dodge sensor and new CPS harness plug and it worked for 4 months. Couple weeks ago engine cranked fine but no start. Tried again and ran fine. A few days ago engine died while driving but started right up. No codes. Had a shop scan and found all to working fine.
Any ideas?
